Often a project can go well except for one thing. A single screw, for example, that doesn't want to go in, or time wasted constantly changing drill bits, can hang up an otherwise perfect project. Investing in specialty tools like those shown here can solve typical problems to help get jobs done right with less time and effort.
When doing tree pruning work, making an extra undercut with your pruning saw will help keep the bark below heavier branches from stripping down and marring the trunk. Make the undercut from below the branch, about 4 to 6 inches out from the trunk. Then cut from the top of the branch, just outside the lower cut. Lastly, use the saw to make a final cut close to the terminal base.
